That is, by creating a new log.

Edit the text to be signed in the log.

As for shiny text, you can set the color of the text to "flash" effect (optional when setting the font color)

Then change the mode to code form (WINDCODE mode) to see all the codes.

Then copy all the code to the place where the space signature is set.

But don't set too many.

Or too complicated.

It is possible to exceed the word limit of signature.
